Raising Awareness of Research Ethics in SoTL: The Role of Educational Developers
Does the subject of research ethics take you by surprise? Does it make you somewhat uncomfortable? Does it seem to have nothing to do with your research or your practice? These are the attitudes we have encountered about research ethics among some SoTL researchers at workshops and conferences. In many cases, these researchers had conducted research that should have undergone research ethics board (REB) review, but did not; that should have included a consent process for the use of student data or previous work, but did not; or that started out as program evaluation and became research without meeting the criteria of ethically acceptable research conduct. In this essay, we will argue that familiarity with our national research ethics Policy: The Tri-Council Policy Statement: Ethical Conduct for Research Involving Humans, 2nd edition (TCPS 2) and how it applies to SoTL, is essential for researchers and for educational developers. We will propose a role for Centre of Teaching and Learning staff in raising awareness of TCPS 2 and we will dispel some of the most common myths and misconceptions that abound regarding SoTL and research ethics.
Le sujet de lâĂ©thique de la recherche vous surprend-il? Vous rend-il quelque peu mal Ă lâaise? Semble-t-il ne rien avoir Ă faire avec votre recherche ou votre pratique? Ce sont des attitudes que nous avons rencontrĂ©es quant Ă lâĂ©thique de la recherche chez certains chercheurs en ACEA dans des ateliers et des confĂ©rences. Dans de nombreux cas, les chercheurs ont effectuĂ© des recherches qui auraient dĂ» ĂȘtre examinĂ©es par les conseils dâĂ©thique en recherche, mais qui ne lâont pas Ă©tĂ©; qui auraient dĂ» comprendre un processus de consentement pour lâutilisation de donnĂ©es sur les Ă©tudiants ou de travaux antĂ©rieurs et pour lesquelles mais ils nâen ont pas, ou qui ont commencĂ© par ĂȘtre une Ă©valuation de programme et qui sont devenues une recherche sans toutefois respecter les critĂšres relatifs Ă la conduite dâune recherche Ă©thiquement acceptable. Dans cet essai, nous expliquons que la connaissance de notre politique nationale dâĂ©thique en matiĂšre de recherche : lâĂnoncĂ© de politique des trois Conseils : Ăthique de la recherche avec des ĂȘtres humains 2e Ă©dition (EPTC 2), est essentielle et nous montrons en quoi elle sâapplique Ă lâACEA. Nous proposons un rĂŽle pour le personnel du Centre dâenseignement et dâapprentissage afin de mieux faire connaĂźtre lâEPTC 2 et dissipons les mythes et idĂ©es erronĂ©es les plus courants qui abondent concernant lâACEA et lâĂ©thique de la recherche
Leaving the Nest: The Evolution of CHRPP (the Course of Human Participant Protection) | Quitter le nid : lâĂ©volution du cours dâĂ©thique sur la protection des participants humains
Four years ago [Institution Name] University launched an online tutorial called CHRPP, the Course in Human Research Participant Protection, and published a paper based about its purpose, design, and usability in (Authors, 2009). CHRPP was originally created to raise awareness among research students about the federal policy regarding research ethics and to encourage ethical research practices. Self-assessments and interactive activities were built into the tutorial to help achieve our goals. Since the first publication CHRPP has been updated based on user feedback from a user satisfaction survey. The generally positive reception of this innovative tutorial led to it serving as the basis of a new national research ethics tutorial hosted by the Government of Canadaâs Panel on Research Ethics. This paper summarizes the evolution of CHRPP from a homegrown solution for [Institution Name] University to an essential piece of Canadaâs national research ethics education program.
En 2008, lâUniversitĂ© Queenâs a lancĂ© un tutoriel en ligne nommĂ© CHRPP (Course in Human Research Participant Protection, cours sur la protection des participants humains Ă la recherche) et publiĂ© un article sur son objectif, sa conception et sa convivialitĂ© dans Balkwill, Stevenson, Stockley et Marlin (2009). Le CHRPP a Ă©tĂ© crĂ©Ă© pour sensibiliser les Ă©tudiants qui font de la recherche sur la politique fĂ©dĂ©rale relative Ă lâĂ©thique de recherche et pour favoriser les pratiques Ă©thiques de recherche. Des autoĂ©valuations et des activitĂ©s interactives ont Ă©tĂ© intĂ©grĂ©es au tutoriel pour nous aider Ă atteindre nos objectifs. Depuis sa premiĂšre publication, le CHRPP a Ă©tĂ© mis Ă jour en se basant sur la rĂ©troaction tirĂ©e dâune enquĂȘte sur la satisfaction des utilisateurs. La rĂ©ception gĂ©nĂ©ralement positive quâa reçue ce tutoriel innovateur lui a valu de servir de base pour un nouveau tutoriel national en Ă©thique de la recherche quâhĂ©berge le Groupe consultatif en Ă©thique de la recherche du gouvernement du Canada. Cet article rĂ©sume lâĂ©volution du CHRPP qui, dâune solution maison pour un Ă©tablissement est devenu une partie essentielle du programme national canadien dâĂ©ducation en Ă©thique de la recherche
Magnetite Biomineralization in Magnetospirillum magneticum Is Regulated by a Switch-like Behavior in the HtrA Protease MamE
Magnetotactic bacteria are aquatic organisms that produce subcellular magnetic particles in order to orient in the earth's geomagnetic field. MamE, a predicted HtrA protease required to produce magnetite crystals in the magnetotactic bacterium Magnetospirillum magneticum AMB-1, was recently shown to promote the proteolytic processing of itself and two other biomineralization factors in vivo. Here, we have analyzed the in vivo processing patterns of three proteolytic targets and used this information to reconstitute proteolysis with a purified form of MamE. MamE cleaves a custom peptide substrate with positive cooperativity, and its autoproteolysis can be stimulated with exogenous substrates or peptides that bind to either of its PDZ domains. A misregulated form of the protease that circumvents specific genetic requirements for proteolysis causes biomineralization defects, showing that proper regulation of its activity is required during magnetite biosynthesis in vivo. Our results represent the first reconstitution of the proteolytic activity of MamE and show that its behavior is consistent with the previously proposed checkpoint model for biomineralization
